Monitoring modes and credentials
Full monitoring, Management only and read-only credential profiles.
Monitoring modes
Full monitoring runs configured background health workers. Management only pauses selected background monitoring while keeping on-demand inventory, operations, audits, automation, troubleshooting and administration available.
Granular services
- Switch availability.
- Stack Member Health.
- Power / UPS.
- Incident detection.
Monitoring Credentials
Profiles can use read-only SSH or SNMPv3. They are stored separately from personal SSH sessions and Automation credentials.
SNMPv3
Portivo uses SNMPv3 authPriv. New profiles prefer SHA-256. SHA and DES remain explicitly labeled legacy compatibility modes. Verification uses sysDescr on a switch or UPS and does not send configuration commands.
Freshness, confirmation and honest state
Switch availability uses low-impact ICMP polling and never opens TCP/22 for background reachability. A healthy switch receives one ICMP echo per normal poll. If it fails, Portivo makes exactly two bounded ICMP retries. In Auto mode, only after all three attempts fail, Portivo may issue one lightweight SNMPv3 sysUpTime.0 request when a monitoring profile is available. SNMP telemetry remains independent from ping reachability. Consecutive-failure confirmation and adaptive offline backoff prevent one transient loss from becoming an incident.
When background monitoring is paused, Dashboard and Power must not present cached values as live. The interface marks monitoring as paused while retaining last-known evidence and scan time. On-demand workflows still collect fresh evidence through their own authenticated sessions.
Capacity controls
Health concurrency, normal and offline intervals and long-offline thresholds are bounded configuration values. Deterministic per-switch jitter spreads probes so large fleets do not poll in lockstep. Increase concurrency only when Portivo and the management network can absorb the additional parallel probes.
